To all whom tt'mcy concern: I

-TBe-it known that I, FRED. GHRIs'rEN, of Homestead, in the countyoffIowaand State of Iowa, have invented certain new and usefulImprovements in Shuttle-Box Mechanism for Looms; and Ido'hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled inthe art to which itpertains to makeand use it, reference being had tothe accompanyingdrawings ,{Which form part of this specification.

My invention relates to an improved shuttle-box mechanism for-looms.

The object of this invention is to provide a with l a shuttle andpositively-reciprocated carriage, of a rotary shuttle-box cylinder andsuitable mechanism, as will hereinafterbe described, whereby the shuttleis taken from the carriage when it arrives near the end of theloom-lathe; and after the carriage has commenced its return movement anydesired 1 shuttle in the cylinder may be delivered to 1. the carriageand carried to the opposite end I of the race.

In the drawings, Figure 1 is a front'view of my improvedshuttlem'otion,a portion of the race being cut away to show the engagement of thesector-gear with the rack attached to; the shuttleecarriage. Fig. 2 is arear elevation.

Fig. ,3 is a plan view. Fig. 4 represents the; outer end of theshuttle-box. Fig.5 showsl the inner end of the same, with the shuttle-1box cylinder raised clear of the race. represents the inner end of theshuttle-motion Fig. 6

with the shuttle-box cylinder resting on the race.

A designates the shuttle-race, and ,B the belt, having acarriage, a,secured thereto,

the same as in the ordinary positive-motion looms. I do not-show anyparticular mech anism for propelling the shuttle, as any of the knownmechanisms employed in positive-motion looms may be employed, myimprovementbeingadapted' for use with any loom of this class. V r I y 0represents the-shuttle-box cylinder, which may have any desired numberofshuttle boxe's b formed therein. In the present example I havershown thecylinder provided with four shuttle-boxes. A shai't passes throughcylinder U, the journals 0 c of said shaft resting in bearings 01 d,which latter are secured to the outer ends of arms 'D D. e p

The opposite ends of the arm'sD ii) are fitted to or sleeved upon thedriving-shaftE, for "a purpose hereinafter described. Gears Fcorresponding in number with the number of shuttleboxes in cylinder G,are loosely mounted upon the driving-shaft E,and kept from lateraldisplacement by means of collars e e Gears Hare arranged to mesh withloose gears 'F on the driving-shaft, and are arranged on, and rigidlysecured to, the cylinder-shaft in such a manner that the cut-awayportion of one gear is opposite the cogs ot' the next gear, and hence bythis arrangement three of the sectional gears are always in engagementwith the loose gear-wheels F on the drivingshaft. Gear wheels H areseparated from eachother by collars y, loosely secured tothecylinder-shaft. Collars g serve as fulcrums for the clutch-levers, thelatter beingpivoted to said collars,whereby theyhave lateral movement tothrow the sliding clutchesin :or-out of engagement withthe loose gearsF. Upon the end of cylinder-shaft G is secured an arrest or stop wheel,I, which is provided with as many notches or depressions h as there areshuttle-boxes in the cylinder, said notches being arranged in line withsaid shuttle-boxes. A spring, J, havingan oblong slot, t, in one end toadmit of varied adjustment, is secured by a clamp-screw,j, or in anyother suitable manner to the arm D, the free end of the spring having ananti friction roller, j, journaled therein. Roller j travels upon theperiphery of the arrest-wheel I, and as the roller j enters one of thenotches h in the wheel the roller serves to lock the cylinder and holdit stationary while a shuttle is being deposited in or taken from ashuttle-box in the cylinder.

The rotary shuttle-box cylinder is raised andlowered as follows:Krepresents a toothed sector, secured to the outer end of acountershaft, k, journaled in bearings beneath the shuttle-race. A restor stop bar, K, is secured to the race, the rest serving to limit themovement of sector K. v

Sector K projects upward into the race, and is operated and turned ineither direction by means of a rack, Z, secured to the side of theshuttle-carriage a. When the carriage approaches the end of the race therack Z secured to the carriage engages with the teeth of the sector andturns the same in the direction of the line of travel of the carriage.Immediately after'the' carriage commences its return movement, the rackZ engages with the sector, and turns it in the opposite direction.-

To the opposite end of the counter-shaft k is secured a cam, m, whichrests upon the free .ends of levers a a, which are pivoted to supports 00. Upon the outer ends of .levers n a rest the vertically-sliding barspp, the upper ends of said levers being forked to receivethe arms D D.

By the arrangement of parts last described itwill be seen that when theshuttle-carriage approaches the end of the race,.and after the shuttlehas been delivered into the shuttlebox-cylinder, the rack on thecarriage engages with the toothed sector turning the same, whichoperation imparts a part revolution to the cam, thus depressing theinner ends of levers n n, and raising the sliding bars 19 p, whichlatter operate to raise the cylinder clear of the race, and allow thecylinder to be revolved, if so desired, to bring another shuttle in linewith the race. When the carriage commences its return movement the rackZ engages with the sector, and turns it in the opposite direction, andreverses the movement of the several parts above described, thuslowering the cylinder, so that the roll ers of the carriage engage withthe rollers of the shuttle, and draw the latter from its box and carryit across to the opposite side of the loom.

It' will be noticed that the periphery or shell q of cylinder 0 extendsslightly over the side walls, of each shuttle-box, as at 1" 1', forminga ledge or flange on each side of the shut-.

tle-box. The opening 8 of each shuttle-box is of sufficient width toallow of the entrance of the rollers of carriage and shuttle, but ofless .width than the width of either carriage or 'tle-box in line withthe race.

shuttle. As the flanges r 4 rest in directcon; tact with the upperportion of the race the carriage conveys the shuttle Within the shut-The rollers of the shuttle project through the opening .9 of theshuttle-box; but as this opening is narrower than the shuttle the latteris securely retained within the cylinder, as it is revolved, to carryany one of the number of shuttles therein contained to the shuttlecarriage. Each shuttle-box is provided with a stopspring, t, or someequivalent device, to prevent the shuttle fromcoming in contact with thegearing on the cylinder-shaft.

""In order to allow the weft-threads to be disengaged from the rotaryshuttle-box cylinder, the inner bearing is formed of the upper and lowersections a u, the upper and fixed sections to being secured to an arm,0, at the highest point attained by the journal of the cylinder in itsvertical movement. The movable sectional bearing a is secured to the armD. When the cylinder is being revolved the journal is supported in thebearing u; but when the cylinder is resting on the race, and a shuttleis being taken from one of the shuttleboxes, then the movable bearingrests on the loom-lathe, as shown in Fig. 6, and the -journal is freedfrom contact with either bearing, thus allowing the weft-thread to passfreely over the journal.

Each one of the clutch-levers is provided with a spring, w, one endofwhich is secured to the clutch-lever, while the outer end of thespring rests against the side of the opposing sectional gear. Thisarrangement serves to keep the sliding clutches disengaged from theloose gears on the driving-shaft, unless the clutch-levers areforced-against the spring to compel such engagement.

The operation of my improved shuttle-motion is as follows: The rotarycylinder having been filled with as many different shuttles as differentcolors are desired in the fabric to be woven, continuous rotary movementis imparted to the driving-shaft E, the looselyfitting gears F remainingin a stationary posi .tion on said driving-shaft until thrown inengagement therewith, as hereinafter described.

The rotary cylinder, in its normal position, rests on the race, and asthe shuttle carriage passes beneath the cylinder the shuttle is delivered into the shuttle-box of the cylinder in line with the race. Thecarriage still keeps traveling toward the endof the race, and justbefore it reaches its limit of movement the rack l, attached to the sideof the carriage,

engages with the toothed sector 70, turning it from right to left. Assector It is rigidly secured to the counter-shaft carrying the cam m,the latter is actuated, and, through the medium of levers a at, bars191), and arms D D, serves to raise the cylinder 0 clear of theshuttle-race.

If it is desiredto use the same shuttle again, the cylinderis notrotated; but if a different shuttle is required, the clutch is moved,which serves to throw the loose gear on the driving-shaft intoengagement with the sectional gear on the cylinder-shaft, which isadapted and arranged to rotate the cylinder a suflicient distance tobring the desired shuttlebox in line with the race. When the cylinderhas attained the proper position, the gear, which has been locked to thedriving-shaft by the clutch, becomes disengaged from the sectional gearas the cut-away portion of the,

latter rests in proximity to the cogs on the revolving gear, and thecylinder is thus brought to a rest, where it is retained in a fixedposition by means of the roller engaging with the notch ordepression inthe arrestwheel.

The shuttle-carriage then commences its return-movement, and when itenters that portion of the shuttle-race situated beneath the cylinderthe rack Z on the carriage engages with thetoothed sector and reversesthe operation of the parts heretofore described, thus lowering thecylinder, which latter again rests on the shuttle-race. The rollers onthe shuttle-carriage then engage with the rollers of the shuttle andconvey the shuttle from its box. As heretofore set forth, theweft-thread is allowed to pass readily from the journal of the cylinderas said journal is freed from its hearing when the cylinder is in itslowest position.

The clutch-levers and springs mounted on the cylinder-shaft are raisedand lowered with the shaft, allowing said levers to engage with, and bedisengaged from, the filling-chain V levers.

I do not limit myself to the exact construction of parts shown anddescribed, as it is evident'that they may be modified in form andrelative arrangement without departing from its travel, serves to raiseor lower said cylinder, substantially as and for the purpose set forth.

3. In a loom wherein the shuttle is actuated by apositively-reciprocated carriage, the combination, with the shuttle-boxcylinder, journaled in vibrating bearings, and mechanism for operatingthe cylinder, of the shuttle-carriage, provided with a rack, and atoothed sector, and mechanism arranged to impart vertical movement tothe shuttle-box cylinder, substantially as and for the purpose setforth.

4. The combination, with the shuttle-box cylinder and supporting-arms,pivoted upon the driving-shaft, of the shuttle-carriage,rack, toothedsector, rock-shaft, cam, levers, and sliding bars, substantially as andfor the purpose set forth. I

5. The combination, with the driving-shaft having gears loosely mountedupon the same, and sliding clutches adapted to lock said gears to theshaft, of the cylinder'shaft, provided with sectional gears, andclutch-levers adapted to throw the gears on the driving-shaft in or outof gear with the sectional gears on the cylinder'shaft, substantially asand for the purpose set forth.

6. The combination, with the loose gears on the driving-shaft, ofsectional gears and collars on the cylinder-shaft and clutch-leverspivoted to said collars, substantially as and for the purpose set forth.

7. The combination, with the cylinder-shaft and mechanism for verticallymoviu g the same, of the sectional bearing for its inner end, wherebythe weft-thread may pass from the journal when the shuttle leaves thebox, substantially as and for the purpose set forth.

8. The combination, with a positively-reciprocated shuttle-carriage anda rotary shuttlebox, the same adapted to be raised and lowered by theshuttle-carriage, of mechanism, substantially as set forth, whereby thecylinder may be actuated to bring any one of its boxes in line with theshuttle-race, substantially as and for the purpose set forth.
